"It fluctuated from three to four and a supervisor," BART's deputy police chief Ed Alvarez said. "That was it. With vacation and time off, it didn’t provide us the staffing we needed that was adequate to ride the trains."

Alvarez said in the past year there’s been an increase in crime throughout the transit system. On Monday, police arrested Mario Washington on suspicion of using bolt cutters to assault a rider in the East Bay and assaulting another rider in San Francisco in what were deemed random attacks.

Oscar Rodriguez is a union representative for train agents and operators. He says they’ve been asking for increased patrols on trains for months, and he's glad to hear the CAP team is fully staffed.
